// 原始查询（php）：
    # $dlist = db()->table('coms_corder')->where("show='1'")->limit(6);
    # $dlist = db()->qeury("SELECT * FROM coms_corder_ys ORDER BY cid DESC limit6");

// 标签(需要编译模板)：
    # {tag:dlist=[List][modid,keres][join,detail][limit,4]}

// 编译后：
    # $T_dlist = $this->tagParse("dlist","List",array(array('modid','corder'),array('show','all'),array('limit','6'),)); 

// 拟简写(不需要编译)：
    # $dlist = tag('dlist','list',[['modid','corder'],[
    'show','all'],['limit','6']]);
    # $dlist = data('corder','',6,''); # v4.7+可用
